The five areas head to head
AI AnalysisFees & Costs
Since February 2026 no maker fees apply on perpetual contracts; takers pay 0.04% on USDT-margined perpetuals and considerably less on USD1 perpetuals. Perpetuals on tokenised equities carry no trading fee. Network fees of the chain in use apply on top and vary by chain. As of August 2026.
Trading fees most recently ran at 0.25% to 0.3% per trade — a multiple of the 0.02% to 0.05% charged by order-book DEXs in the same comparison. Network fees on Optimism are low by contrast. Given the transfer into the Synthetix offering, terms should be checked directly before trading. As of August 2026.
Usability & User Experience
The interface follows centralised exchange conventions and is quick to navigate for anyone with futures experience. Access is by wallet connection without registration. Traders using several chains need to watch collateral and gas conditions on each. As of August 2026.
The interface was functional and tailored to synthetic trading. Anyone starting today should account for the transition to Synthetix and begin there rather than rely on a brand that is being retired. As of August 2026.
Features & Offering
Aster combines perpetuals on cryptocurrencies with perpetuals on tokenised equities and metals. Alongside market, limit, stop-loss and take-profit orders it offers hidden orders and grid trading. A distinguishing feature is yield-bearing collateral: posted capital can continue to earn while a position stays open. As of August 2026.
Kwenta tracked more than 40 synthetic assets built on the Synthetix protocol, most recently on Optimism. Following the acquisition the interface is being folded into the Synthetix offering and the native token is set to cease to exist. No new features are to be expected for Kwenta as a standalone product. As of August 2026.

Verdict
In our overall rating Aster leads with 4.7 against 2.5 for Kwenta.
For most investors Aster is therefore the better choice.
Aster emerged from the merger of Astherus and APX Finance and positions itself as the multi-chain alternative to single-chain perpetual DEXs. Trading spans BNB Chain, Ethereum, Solana and Arbitrum, settlement stays on-chain and custody stays with the user.
On pricing, Aster moved in February 2026: makers pay 0% on perpetuals, takers 0.04% on USDT-margined perpetuals, and perpetuals on tokenised equities carry no trading fee at all. Collateral posted in certain forms continues to earn yield while a position is open.
The advertised 1001x leverage is mainly a marketing signal and is barely usable in practice — liquidation thresholds at that level are extremely tight. The platform holds no EU authorisation; perpetuals sit outside MiCA in any case, and tax reporting rests entirely with the user. Aster is worth a look for experienced traders who want several chains from one interface.
Kwenta is no longer a standalone platform. Synthetix acquired the trading front end in order to run the interface and user experience itself, and the KWENTA token is set to cease to exist as part of that. Trading remains functional for existing users during the transition, but the brand is being folded into the Synthetix offering.
Substantively, Kwenta always concerned synthetic perpetuals built on Synthetix, most recently on Optimism, covering more than 40 tracked assets. Fees of 0.25% to 0.3% per trade sat far above the order-book DEXs — a disadvantage that sharpened as cheaper competitors advanced.
There is therefore little case for starting here. Anyone wanting to trade synthetic perpetuals from this ecosystem is better served going directly through Synthetix. The venue holds no EU authorisation and tax reporting rests entirely with the user.
